WebSquaric acid (FR-0532), is also called quadratic acid, because its four carbon atoms approximately form a square (cyclobutene). It is a highly acidic, white, high melting crystalline powder. Frinton Laboratories, Inc. offers this in small to medium quantities, as a free-flowing crystalline powder, melting at above 300°C and with purity higher than … WebHowever, the degradation of DNCB in dinitrophenol compounds in vivo, may be considered as a main drawback of this method. Since there is little information concerning the mutagenicity and toxicity of DNCB as yet, we suggest to prefer the use of other chemical compounds, such as dibutyl ester squarate, that act the same way as the DNCB does.
